Then you fly a "composite route." Lay off the great circle, on a globe, gnomic chart, or, last resort, compute it. See if there are dangers or travelling into high latitudes. Then plot the points where the GC crosses that limiting latitude and then sail the GC to the first point, a rhumb line between those points and then the GC for the rest of the voyage.

In the marine world, they may also  be good reason other than weather to
not travel a great-circle route. Icebergs for one.
